Abstract
Abstract The internal connections between cell elements of a multi-cell storage battery is effected by forcing and rotating a metallic connector member through a metallic extension of a first cell element, through the intercell partition and into a metallic extension of the second cell element. In so doing, the metal of the insert is thermally fused to the metal of the two metallic extensions.
